/**
* This file is shared between server and client.
* ⚠️ DON'T PUT ANY NODE.JS OR BROWSER-SPECIFIC CODE IN HERE ⚠️
*
* Note: This uses Flow comment syntax so this whole file is actually valid JS without any transpilation
* The reason I did that is because create-react-app doesn't transpile files outside the source folder,
* so it chokes on the Flow syntax.
